Re: vfork always fail problem

[Huang Bambo]

I truly find the problem.
The path to the executable have Chinese character.
My windows's default language is gbk.
If I use utf-8 encoding for the shell, fork fail. If i use gbk, everything
goes fine.
The following is the test .

[ba...@bambo-notebook ARM9]$ pwd
/cygdrive/d/个人研发/ARM9
  ^^ Chinese directory name

[ba...@bambo-notebook ARM9]$ export LANG=en_US.UTF-8
[ba...@bambo-notebook ARM9]$ ./tvfork.exe
  3 [main] tvfork 4900 fork: child -1 - CreateProcessW failed, errno 2
vfork failed.: No such file or directory
[ba...@bambo-notebook ARM9]$ export LANG=en_US.GBK
[ba...@bambo-notebook ARM9]$ ./tvfork.exe
I'm parentI'm chield.

Re: strftime %b is broken on ja_JP locale

Windows has a bug in Japanese and Korean locales. In these
locales, strings reterned by GetLocaleInfoW for
LOCALE_SABBREVMONTHNAME* miss suffixes representing a month.

It should return "5\u6708" in Japanese and "5\c6d4" in
Korea. MSDN in Japanese describes so. It, however, returns "5"
in both locales. In Chenese, it returns "\u4e94\6708" with the
suffix.

We can solve this problem with LOCALE_SMONTHNAME* instead of
LOCALE_SABBREVMONTHNAME* in these locales. I attathed the patch.

I've been using the native W32 port of emacs for years. I tried using

bind all key combinations.
- Alt+F3 (or Alt+any F-key) seem to have no effect at all.

Are you using emacs in the Cygwin console? If so, many key combinations
won't work as you expect. This is documented in
/usr/share/doc/Cygwin/emacs.README. You'll have better luck running
emacs in mintty. Or for an interface that is more like the native Win32
build, run emacs under X11.

Ken


Sorry, I should have been more clear, I'm running in mintty.
[reading emacs.README ...]
Oh, I see. Is there any way to bind the resulting key codes? Can I use
"M-[ 1 ; 8 u" as a key to bind?



To answer my own question: Yes, you can use
(global-set-key (kbd "M-[ 1 ; 8 u" ...))
to bind Ctrl+Alt+Shift+5 in mintty.

So, now that I know a better work-around, is this a bug in cygwin,
mintty, or cygwin-emacs?


I don't know the answer.  I tried Ctrl+Alt+Shift+5 in emacs under X11, 
and it seems to work fine, i.e., it is recognized as C-M-%.  I also 
tried it in an xterm window ('emacs -nw'), and it fails there but in a 
different way than in mintty: emacs sees it as C-%.


Maybe Andy (mintty author/maintainer) can explain what's going on.

It looks like the stackdumps I sent may be due to secondary crashes.

The problem appears to be cygwin 1.7-specific. (*)

I get a stackdump as follows. I find that I get a stackdump under a
cygwin shell (DOS terminal) but not under mintty so I'm not 100% sure
the stackdump is for the correct error.

I was able to get a further stack trace from gdb from that. Again, it
would only happen on a cygwin shell and not mintty so I'm not sure I

(*) I know that doesn't mean that it's 1.7's fault. Perhaps the
problem was pre-existing and was only revealed in 1.7. But it works in
1.3 and 1.5 on WinXP and fails in 1.7 in WinXP-32, Vista-32, Win7-67.

"M-[ 1 ; 8 u" as a key to bind?



To answer my own question: Yes, you can use
(global-set-key (kbd "M-[ 1 ; 8 u" ...))
to bind Ctrl+Alt+Shift+5 in mintty.

So, now that I know a better work-around, is this a bug in cygwin, 
mintty, or cygwin-emacs?

Are you using emacs in the Cygwin console? If so, many key combinations
won't work as you expect. This is documented in
/usr/share/doc/Cygwin/emacs.README. You'll have better luck running
emacs in mintty. Or for an interface that is more like the native Win32
build, run emacs under X11.

Not only that, but if you pipe that output to another process, you
(or should I say "I") get a stack dump:

Cygwin> ls
Cygwin> cat 
/proc/registry/HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/SystemBootDevice
multi(0)disk(0)rdisk(0)partition(2)Cygwin>

It seems to be reliably repeatable.

Services is fine. Your comment about the firewall caused me to double
check that. Once I started down that road I quickly found the problem.
In the same time frame that I updated Cygwin versions corporate
switched us from Symantec to McAfee. The new McAfee stuff added a
firewall which I'd not configured to allow ssh. Thanks for the
comments and shining a light in the dark corner I'd neglected.

Check the service to see if it's configured using "Services"
under "Administrative Tools" in the control panel.  If it is
you might want to check the firewall, but it sounds like it

Examining /etc/sshd_config:
Port 22
#ListenAddress 0.0.0.0
#ListenAddress ::

So the Listen address appears to be defaulting to whatever sshd is
internally configured to use.

Take a look at the source code for Cygwin's cygcheck.cc.  It checks for
existing Cygwin installations by scanning the registry.  The registry
locations did change between Cygwin 1.5.x and 1.7.x but it should still
be relatively straightforward.  You can also look at setup.exe which
also does some checks.

The other alternative is to just bundle cygcheck.exe and use that in
your script.  As long as you're using this only inside your company
and there is no possibility that it will be distributed, you don't
even have to worry about making source code available to your inhouse
users.

Determining if cygwin is installed on a system

[Spiro Trikaliotis]

Hello,

I have been tasked with generating a script and installing it on all the
machines on our corporate network. For this, I want to use Cygwin.

One of the requirements is that people should be able to install it as
easy as possible. I am thinking about installing cygwin with a .BAT
file.

However, before doing this, I want to determine if there is already a
cygwin installed. In this case, I want to instruct the user to do it on
his own (people who already have cygwin installed are more technically
savvy, and more likely that they would NOT want me to mess with their
system). On the other systems, I would either use setup.exe with
command-line parameters, or just copy the needed files (yes, I know the
latter is not supported.)

Thus, my main concern now is: How can I determine if a version of cygwin
is installed? I could search for cygwin1.dll on the whole system, but
this would need some time. I could look into the path only, but then, I
might miss a cygwin1.dll.

Does anyone have a good idea? I should be able to determine at least
cygwin 1.5 and 1.7.

Thank you for every hint and suggestion.

Best regards,
Spiro.

Reading /proc/registry/... returns extra char

[Dale Stimson]

Reading a file under /proc/registry returns an extra character at the end,
which appears to be the null character.

This has happened for every registry entry that I have tried.  Here  is
one in particular:

$ cat >a.dat 
/proc/registry/HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/SystemBootDevice

$ od -c a.dat
000   m   u   l   t   i   (   0   )   d   i   s   k   (   0   )   r
020   d   i   s   k   (   0   )   p   a   r   t   i   t   i   o   n
040   (   2   )  \0


or even
$ vim 
/proc/registry/HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/SystemBootDevice

which shows its buffer (with "^@" representing the null character) as:
multi(0)disk(0)rdisk(0)partition(2)^@

This problem was first observed after I recently upgraded to cygwin 1.7.5-1.

The problem still occurs if /bin/cygwin1-20100507.dll is dropped in as 
/bin/cygwin1.dll.

Perhaps this problem was introduced by the recent fix which was noted by:

It's fine if you were comfortable with more of your environment seeping
through the 'ssh' connection.  But your comfort is not really the issue.
Exposing specifics about your environment opens any connection up to
exploitation.  This is true for 'ssh' in any environment.  Check the

more details.

Well, maybe you can ask for latest released stable version: 4.7.0.5 [1]

mc.README file will give you more information.

I have using source compiled 4.7.0.4 for a while now without

Yes, it would be obvious if you looked. It simply has a drop down box
that lets you choose the header color, font type or page width (please
look before making assumptions). I could have provided a list of links
with each slight variation or I could have quickly coded this tool to
let the user play with the combinations - I think this makes it easier
and it only took me a few minutes.

I don't see why not, but then I also don't see the point of that.
There are very few images used in my sample, and those that are used
are only there for aesthetics - they convey nothing important. Even
the title is text driven, unlike the current site.

I'm confused here. Design what exactly? My proposed website was coded
entirely using a text editor. No serious web developer uses GUI
programs.

No images were used to convey information. The website can be
translated into other languages very easily while retaining the look
and feel. As with all websites I build, presentation is separate from
content. This means we can simply apply a different style sheet to
change the way the site renders (if we chose to), but that wouldn't be
necessary for this Website. It is such a simple site that it can be
viewed on any device you like as it is - feel free to try it out in
lynx via Cygwin. As an example of the site's versatility, you will
enjoy a convenient "skip to content" link that magically doesn't
appear on the site when viewed in a graphical web browser such as
Firefox. I have no doubt improvements could be made to the text-only
version, and I'd be more than happy to make those.

As I said, only a text editor has been used to build the site.

Cheers,

Problems with environment variables in Windows 7

[yoni shalom]

I don't get the user's environment variables while in ssh session.
Example :

//open up cygwin console
y...@yonidesk ~
$ env | grep -i ProgramFiles
COMMONPROGRAMFILES=C:\Program Files\Common Files
PROGRAMFILES=C:\Program Files
y...@yonidesk ~
$ ssh y...@localhost
Last login: Thu May 13 13:45:01 2010 from ::1
y...@yonidesk ~
$ env | grep -i ProgramFiles
[nothing]

Fresh install of latest cygwin, everything else otherwise seems to work.
Any clues ? Thanks.

I haven't looked at this but what is a style changer tool ( would it
be obvious if I looked? Just change style sheets or something). My
point here is not to ask random
questions about tangential topics but this highlights
an important area of command line tools for graphical
desgin needs. Could you build all the artwork and generate all the html
from command
line scripts and give these scripts various parameters so that variations
could beconsistently generated using general rules? One objective
beyond making cool pictures may be to see how well you can automate
and design without a GUI program. I have nothing against pointing
but it is easier to describe typed chars than mouse moves to relate
your wisdom to others.
As far as that goes, if you could reduce an arbitrary image to ASCII
art algorithmically  to produce things beyond hippos, "fingers" and
homer simpsons, that may be an interesting study in image compression,
perception and maybe searching/indexing.

This isn't just academic or banter or whining about saving a few bytes
when everyone knows the speed of light is increasing each day,
but lets say you wanted to generate web pages for wireless, unusual
locales,  or other
devics that have some fixed relation to your main pages and don't want
to redesign them etc.

Using cygwin to design and generate the site would be a good result in itself :)

" No mice were killed in the construction of this site" LOL.

Oh, right. Forgot about that. Sorry for FUDing...

Cygwin is actually GPL2-with-linking-exception, so software under any
OSI-approved license is compatible with Cygwin:

Bashes marked with 'I' appear so many times  how many times you run and 
exit MC.


I run MC through 'mintty -e mc --subshell'.
After some count (~10-12 ???) of run and exit form MC I got error
(recorded not literary): "no free pty available".

So MC MUST kill subshell after exit.
